Title:
MICROALGA DISPERSION AND PREPARATION METHOD OF MICROALGA DISPERSION
Document Type and Number:
WIPO Patent Application WO/2023/171387
Kind Code:
A1
Abstract:
A method for preparing a microalga dispersion from a microalga-containing liquid that contains a microalga having a length of less than 1000 μm, said method including a concentration step for cross flow-filtering the microalga-containing liquid using a hollow fiber membrane, wherein, in the cross-flow filtration in the concentration step, the circulation linear velocity is within the range of 0.2-1.3 m/sec. inclusive.
